Innovacera Always Have Different Silicon Nitride Ceramic Balls Sizes In Stock

Innovacera develop all kinds of ceramic balls including the zirconia ceramic and silicon nitride ceramics. Many silicon nitride balls have stock.

Silicon nitride ceramic balls are precision ceramic balls which is forming in non-oxidizing atmosphere with high-temperature sintered. At 800 ℃, the strength, hardness almost unchanged, the density is 3.20g / cm3, only 1/3 weight of the steel bearing, when rotating, the centrifugal force is small, can achieve high-speed operation. It can be used to non-lubricating medium with high pollution environment. It is ceramic bearings, hybrid ceramic ball bearings preferred balls. So it is widely used in the Bearing ,Chemical , Oil Industry


  • High strength
  • High wear resistance
  • Excellent self-lubricating
  • High electrical insulation
  • Resistance to high temperature
  • Good magnetic insulation performance
  • Corrosion resistance, resisting acid and alkali, it can be long-term used in seawater.
